The Nikon AF-S NIKKOR 180-400mm f/4E TC1.4 FL ED VR is a pro-spec telephoto zoom and the first Nikon lens to feature a built-in 1.4x teleconverter. Rather like Canon’s EF 200-400mm f/4 L IS USM with internal 1.4x extender, the focal length of the lens can be extended by the flick of a lever.

It covers a broad 252-560mm range on a full-frame DSLR with the converter dropped in, or 378-840mm on a DX-format DSLR. The lens features a constant maximum aperture of f/4 when the built-in 1.4x teleconverter isn’t being used, which closes to f/5.6 when the in-built converter is deployed.

Replacing the older AF-S 200-400mm f/4G ED VR II, the AF-S NIKKOR 180-400mm f/4E TC1.4 FL ED VR weighs just 140g more, at 3500g, despite the addition of the extender. It features Vibration Reduction which offers four stops of image stabilisation, even with the extender engaged, while a Sport VR mode and advanced AF tracking help the lens to lock onto and maintain focus with fast moving subjects.

Aimed at working professionals shooting sports and wildlife in demanding environments, the lens has a robust magnesium alloy body. Every moving part of the lens barrel is fully weather-sealed and a fluorine coating helps repel water dust and dirt. The price of the lens at launch is £10,999.
